What are WebSockets | How is it different from HTTP? 

This is the way to do it, show it in the real world, seeing is believing, not just with pictures and explanations, great job!

One of the amazing explanation about how the HTTP and web sockets work under the hood. Really appreciated, amazing work done

One of the best videos on YT for Network Engineers.

One of the most amazing video that I have came across on websockets. Rather than directly jumping on to the code - its very important to figure out the reason why web sockets exists- thanks for explaining that.

This is the easiest and the best explanation ever so far i have encountered about this topic...

Best Tutorial because of the fact that you showed real life examples of how that works. Its like a realtime Database but faster

Simply great ! Explained in the easiest and yet most effective way !

Really awesome, aaj pata chala ki WebSocket bhi kuch hota h.

this is exactly what i wanted! thank you so much!

Thanks for this video. It explains alot. Question: Should we socket be used for video streaming? Does using websocket increase data cost? What about speed?

Nice demonstration of web sockets.

Most amazing and highly depth and best video.. Ver issue to understand end to end

Prime quality video!!! You know how to make people understand new concepts. I am going to follow you just to improve my teaching skills. Keep it up!

Very well explained with examples. Thank you!

Best video on websockets ever

So informative and easy to understand, I almost feel guilty it is free! Well almost!

thanks for the very practical explanation

Thank you so much sir, your explanation is perfect.

Simply superb video. Thank you. God bless you..

This was great! Thank you very much.

Excellent stuff man!

Extremely clear. Thanks man.

its really nice videos i had across till now very simple Explanation with comparison with the HTTP protocol. I can say very useful for to understand the web socket and why to go for and why to not Thanks for posting such interesting videos please keep it ahead so we can gain our existing technical skills.

We’ll wonder full presentation and explanation 🎉❤

Great explanation! Thank you!

Amazing explanation of web sockets & usage 👍🏻

Great flow! Really appreciated your efforts.

Nice and cear explanation. Thank you.

Nice video. Do you have a video where you implement WS?

concise and well articulated

awesome. you have shown how the things work in real time also. Thanks

Superb explanation 👌

Good explanation, Bravo.

Very Good Explanation.

Examples were very useful

@tech primers - for the chat application, you are saying everytime we refresh the browser the data will be lost since the connection is lost. It doesn't happen like that in Whatsapp right? What is different in whatsapp then?

Good fundamental concepts. I have a unique requirement. API sends huge amount of data to UI and sometimes it throws "Broken pipe error" from backend, sometimes UI can't get whole response though response is 200 OK . Can I use it here ?

Great video as always could you pls make videos on system design of popular applications

1 - before web socket how chat system works real time like (fb) 2 - how counter strike 1.6 old one works ( its chat system ) 3 - web sockets sending empty payload to servere in case of idel ? 4 - when client connect to server , where servere strore this client is connected ?

Amazing intro to WebSockets

In the stocks example, the JSON messages which are created, are they delivered using a HTTP packet?

How can we check the Web Sockets performance? I want to produce data, but how much ms does it take?

Well explained. Nice work !!!

What software do you use to record your screen? is it Quick Time Player? How do you zoom?

Very well explained ! Thanks for the video, you've earned a sub mate :)

Simply amazing 👏👏

Thanks for the simple explanation.

Great video, appreciate the time and efforts. One off-topic question though... How did you make that intro? It looks amazing.... thanks in advance.

Great! Next video would be explain integration with spring and website?

So we can't store the messages on database using Web sockets?

Thanks, bro for such a nice explanation.

Thank you so much. This was worth watching.

How resource intensive is keeping a websocket open over just using REST calls every 20 seconds or so? That's the one thing I have not been able to wrap my head around with sockets is how much RAM do I need for a live app that could have X amount of concurrent connections at any given time.

This is a truly good explanation, thank you.

Well explained !

Nice tutorial. thanks.

Woow. Great video. Thank you

Thanks for the video. Simple and great Explanation.

Does it use UDP as means of Transport of OSI model?

Informative. Please provide a implementation of this with angularjs and spring rest

Great explanation

Thanks, it's a good explanation, very useful

Can SSE be also be used to push the data from Server to Client? Why only WSS in case of gdax example

can you plz make a vid tut on how to make a web socket node js via php secure with cert and key files ? and have you got github link to the code you used?

very good explanation. thank you for such a nice video.

Nice and short intro on websockets!

What will happens if we trying to bind large set of data into UI? Is browser hangs?

Superb explanation..

Great topic 👍

Great presentation, Thanks!

Excellent Video. Thanks!

Could you provide a good implementation example for JS?

great video! one big thank you!

Thank you TechPrimers

could you please upload some videos on spring batch

When you refresh a page, does the browser notify the server to forget about the old websocket connection. How does server know that not that connection is invalid now.

thank you , good explanation.

awesome explanation

very nice video....

The explanation is okay but you should use some animations/whiteboard etc to help the viewers visualize the concepts.
